all these produce pixel-images, not x,y vector lists.
it is true that all your shape analysis objects provide a large
toolset to make shape pattern analysis/recoginition; but it is useful
in many cases – analysis and processing – to have a vector based
ouptut of blobs.

max/jitter SDK…

yes, mail it!
